The characteristics of fabrics and the identification of the materials of the constituent materials such as the cover fabric and the bookstring of the old documents collected in the Kyujanggak were investigated and analyzed. The results were recorded and used as basic data for repair restoration. For this purpose, morphological observation of fabrics and fibers was carried out and spectroscopic analysis was conducted. All textiles used in the marking of the documents were made of plain weave. The fibers were made of silk, cotton and bast fiber. The fabric of the front cover 2(Kwanghae-ilnyeongiyu-Ulsan-hojeogdaejang) was examined identified in a modified derivative plain weave. The degradation of the fiber was observed, As a result of IR analysis, a peak estimated to be due to oxidation was observed and the degree of crystallization of the cotton fiber was high higher than those of original(fresh/control) ones. The bookstrings was were made by twisting cotton, bast, and a silk thread. The silk thread was made of Z twist, and the string made of cotton yarn and bast yarn, was made of S twist. 규장각에 소장된 고문헌-탁지정례, 상방정례, 소현분조일기, 승정원일기, 영조정순후사존호장조헌경후재돈호도감의궤, 십칠사찬고금통요 외 15권-의 표지 직물과 책끈 등의 구성재료의 직물 특성과 소재를 조사 분석하고 그 결과를 기록하였다. 이를 위해 직물과 섬유의 형태학적 관찰을 실시하고 분광분석 조사를 실시하였다. 문헌의 표지에 사용된 직물은 모두 평직으로 조성 섬유는 견섬유와 면섬유, 마섬유가 사용되었다. 이중 『광해일년기유울산호적장』 앞표지 2의 직물은 경위사를 2가닥으로 사용하여 직조한 변화평 직으로 조사되었다. 섬유가 절단되는 등의 손상이 많이 관찰되었으며, IR 분석결과 산화에 의한 것으로 추정되는 피크가 관찰되었으며 면섬유의 결정화도가 크게 나타났다. 피복사인 『성종왕류부록』 의 책끈을 제외한 문헌의 책끈은 면사와 마사, 그리고 견사를 꼬아 제작했으며, 견사는 Z꼬임으로, 면사와 마사로 제작된 끈은 S꼬임으로 만들어져있는데 섬유 종류에 따라 구분하여 제작한 것으로 생각된다.

북한이탈주민의 자기고양 편파가 남한 내 심리적 적응에 미치는 영향

채정민,한성열 한국문화및사회문제심리학회 2003 한국심리학회지: 문화 및 사회문제 Vol.9 No.2

The purpose of present study is to investigate what is the most important factor among personality, social relation perception, and cultural influence on North Korean Defectors' self-enhancement bias, and how their self-enhancement bias influences on their psychological adaptation in South Korea. To implement this, we compared the self-enhancement bias of South Korean undergraduates and North Korean Defector undergraduates, and social desirability, too. However, there was no significant result. Based on this outcome, we focused on 121 North Korean Defectors' self-enhancement bias mechanism. We found that personality and social relation perception factors influenced significantly on their self- enhancement bias and furthermore their self-enhancement bias affected on their psychological adaptation. In addition to this, we identified sex difference at this mechanism. That is, women showed the same pattern with the existing findings in the study of self-enhancement bias mechanism, but men showed somewhat different pattern. 본 연구는 북한이탈주민들의 자기고양 편파가 성격, 사회적 관계, 문화적 측면 중 어느 것에 의해 더 많이 영향을 받는가를 확인하고, 이 자기고양 편파가 우울감과 생활만족감이라는 심리적 적응 지표에 어떻게 영향을 미치는지를 확인하기 위해 이루어졌다. 이를 위해 먼저 북한이탈주민들과 남한 주민들이 자기고양 편파와 문화적 측면에서 얼마나 유사한 수준을 보이는지를 확인할 필요가 있어서 북한이탈주민 대학생과 남한 대학생들을 대상으로 자기고양 편파 수준과 사회적 바람직성을 비교하였는데, 유의미한 차이를 보이지는 않았다. 이 결과를 바탕으로 북한이탈주민 121명을 대상으로 자기고양 편파에 영향을 미치는 3가지 측면의 영향력 비중을 확인하기 위해 중다회귀분석을 실시하였는데, 지각된 사회적 지지와 낙관성의 순서대로 높은 설명력을 보였다. 지각된 차별감과 사회적 바람직성은 자기고양 편파와 유의미한 상관을 보였지만, 회귀분석에서는 설명량이 유의미하지 않은 것으로 나타났다. 그리고 북한이탈주민의 자기고양 편파는 우울감과 생활만족도 모두에게 부적인 유의미한 설명력을 보였다. 이러한 결과는 주로 남자 북한이탈주민들이 보인 경향성을 반영하는 것으로서 주목을 끄는 것이다. 반면에 여자 북한이탈주민들이 보인 경향성은 기존의 연구 결과와 유사한 것이었다.

Background : Since the human genome project was completed in 2003, there have been numerous reports on cancer and related markers. This study was aimed to develop a system to extract automatically information regarding the relationship between cancer and tumor markers from biomedical literatures. Methods : Named entities of tumor markers were recognized by both a dictionary-based method and machine learning technology of the support vector machine. Named entities of cancers were recognized by the MeSH dictionary. Results : Relational and filtering keywords were selected after annotating 160 abstracts from PubMed. Relational information was extracted only when one of the relational keywords was in an appropriate position along the parse tree of a sentence with both tumor marker and disease entities. The performance of the system developed in this study was evaluated with another set of 77 abstracts. With the relational and filtering keyword used in the system, precision was 94.38% and recall was 66.14%, while without the expert knowledge precision was 49.16% and recall was 69.29%. Conclusions : We developed a system that can extract relational information between a tumor and its markers by incorporating expert knowledge into the system. The system exploiting expert knowledge would serve as a reference when developing another information extraction system in various medical fields. (Korean J Lab Med 2008;28:79-87)

채정민,유효선 한국문화재보존과학회 2015 보존과학회지 Vol.31 No.3

본 연구는 1996년 천안시 유량동에서 출토된 분홍색 단령의 염료 동정을 통해 조선시대에 사용된 적색 염료를 실증하기 위한 것이다. 이를 위해 유물에 사용된 염료를 추출하고 이것을 당시 염색에 사용되었을 것으로 추정되는 적색계 염료(홍화, 소목, 꼭두서니)에서 추출한 염료와 함께 고성능액체크로마토그래피분석을 실시하였다. 그 결과 유물에서 추출한 염료와 홍화염색포의 추출 염료는 같은 시간대인 17.5분에서 피크가 나타났다. 이때 자외/가시선 분광분석 결과는 두 시료 모두519 nm에서 최대흡수파장이 나타나 기존 홍화의 홍색소 분석 결과와 같은 것으로 조사되었다. 또한 negative ion mode에서 질량분석을 실시한 결과 유물과 홍화 염색포에서 추출한 염료 시료는 carthamin의 분자량인 910을 나타내는 m/z 909에서 같은 시간대의 피크가 확인되었다. 이와 같은 결과로 이 분홍 단령 직물을 염색하는데 사용된 염재는 홍화인 것으로 동정되었다. Aim of this study is to identify dyestuff of the Dallryeong(official’s robe in Joseon Dynasty, 16th century) excavated from Yuryang-dong, Cheonan, in 1996. For this purpose, extracted dyestuffs from Dallryeong fabric and from natural dyestuffs for red color(safflower, Sapanwood, Madder) which are presumed to have been used in the Dallryeong, are analyzed and compared by high performance liquid chromatography(HPLC). As a result, HPLC chromatogram of extracts of the Dallryeong’s dyestuff and safflower are showed a peak at 17.5 minutes. The UV/Vis spectra of the samples are showed the maximum absorption wavelength at 519nm. This result is identical with the analysis of the previous studies on red dyestuff of safflower. In addition, the analysis of Mass Spectrometry(MS) showed the identical result of the peak with m/z 910. Following these results, excavated pink Dallryeong were considered to have been dyed with safflower.

$ZrB_2$ has a melting point of $3245^{\circ}C$ and a relatively low density of $6.1\;g/cm^3$, which makes this a candidate for application to ultrahigh temperature environments over $2000^{\circ}C$. Beside these properties, $ZrB_2$ is known to have excellent resistance to thermal shock and oxidation compared with other non-oxide engineering ceramics. In order to enhance such oxidation resistance, SiC was frequently added to $ZrB_2$-based systems. Due to nonsinterability of $ZrB_2$-based ceramics, research on the sintering aids such as $B_4C$ or $MoSi_2$ becomes popular recently. In this study, densification and high-temperature properties of $ZrB_2$-SiC ceramics especially with $B_4C$ are investigated. $ZrB_2$-20 vol% SiC system was selected as a basic composition and $B_4C$ or C was added to this system in some extents. Mixed powders were sintered using hot pressing (HP). With sintered bodies, densification behavior and high-temperature (up to $1400^{\circ}C$) properties such as flexural strength, hardness, and so on were examined.

북한주민에 대한 효과적인 블렌디드 러닝 방안과 정책 방향

The importance of education in unifying nation is well known via the case of Germany already unified. Unified German government consumed billions of dollars in the area of the public education and career re-education for East Germans. In considering current Korean situation, education support for the North Koreans will be necessary. Then, the most important issue is how to support the North Koreans' education. Blended learning can be the answer. Blended learning is proved educationally efficient and effective. For success of the North Koreans' education via blended learning, at first, it needs to study systematically the benefits and conditions for the successive learning via blended learning. In this study, the way to operate blended learning for the North Koreans is suggested, based on the understanding of blended learning. It can be said that we can decrease tremendous government budget annually for the North Koreans' education support through blended learning. 국가 통일 과정에서 교육의 중요성은 이미 통일을 이룬 독일의 사례에서 충분히 알게 되었다. 서독 중심으로 진행된 통일 과정에서 동독주민을 상대로 한 학교교육과 직업재교육 등의 분야에서 천문학적 교육비를 지출했다. 한국도 통일을 고려할 때 한국이 북한을 흡수통일을 하지 않는다고 하더라도 북한주민의 교육지원을 어느 정도 해야 할 상황이다. 그렇다면 북한주민을 위해 어떠한 방식으로 교육지원을 해야 하는가가 문제인데, 최근 들어 교육효율성뿐만 아니라 교육효과성이 검증된 블렌디드 러닝(blended learning)이 최적의 대안으로 거론되고 있다. 이 블렌디드 러닝을 통한 북한주민의 교육을 성공적으로 이루기 위해서는 블렌디드 러닝을 통해 얻을 수 있는 편익과 성공 조건을 체계적으로 연구할 필요가 있다. 이에 본 연구는 블렌디드 러닝에 대한 이해를 기초로 북한주민을 위한 블렌디드 러닝 방안을 제시하고, 이를 통해 연간 최소 수천억 원에서 최대 수조 원, 한 세대 정도의 통일 기간이 필요하다는 점을 고려하면 수십조 원의 교육예산을 절감할 수 있음을 제시하였다.

LB-9, Novel Probiotic Lactic Acid Bacteria, Ameliorates Dextran Sodium Sulfate-Induced Colitis in Mice by Inhibiting TNF-α-Mediated Apoptosis of Intestinal Epithelial Cells

채정민,장문한,허완,조형택,이동훈,황보별,김진우,윤석민,양시영,이진협,김영준 한국식품영양과학회 2019 Journal of medicinal food Vol.22 No.3

Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease, is a group of chronic and relapsing inflammatory conditions within the gastrointestinal tract. An increase in intestinal epithelial cell (IEC) apoptosis is a major characteristic of UC. Tumor necrosis factor-α (TNF-α) plays an essential role in the regulation of apoptosis. Aberrant activation of the immune response to resident microflora contributes to overproduction of TNF-α in the mucosal tissue of the gastrointestinal tract; a hallmark of UC. There are no curative medications for IBD. Thus, establishment of novel strategies for the treatment of this disease is imperative. Lactic acid bacteria (LAB) have been characterized as probiotics that can alleviate imbalances in indigenous microflora in UC, exhibiting beneficial effects for the treatment and prevention of IBD. In this study, we elucidate the potential of LB-9, a novel probiotic LAB, to protect against colitis development using a dextran sodium sulfate (DSS)-induced mouse model of UC. Treatment using LB-9 reduced clinical symptoms of colitis. In addition, both colitis-induced and NF-κB-mediated IEC apoptosis was markedly reduced in mice treated with LB-9. Moreover, these results were closely associated with reduced TNF-α levels. Our study demonstrates that the LB-9 probiotic exhibits therapeutic potential for UC through suppression of TNF-α-mediated IEC apoptosis in a murine DSS-induced colitis model, with important biological implications for treatment of IBD in humans.
